COLLAPSIBLE AVNING OR CANOPY FOR CHAIRS.

To all whom it may concern Be it known that I, JASPER GRISSIM, a citizenof the United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented a certain new anduseful Improvement in Collapsible Awnings or Canopies for Chairs, ofwhich the following is a specification.

My invention relates to new and useful improvements in collapsibleawnings or canopies for chairs, and has for its object to provide anexceedingly simple and effective device of this character to be used incombination with a chair which may be readily and quickly applied to theback of a chair so that the person occupying said chair will be shadedfrom the rays of the sun.

A further object of the invention is to produce an awning or canopywhich is adapted to be mounted upon a chair, but when not in use to befolded back out of the way.

With these ends in view, this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claims.

In order that those skilled in the art to which this inventionappertains may under-- stand how to make and use the same, I willdescribe its construction in detail, referring by letter to theaccompanying drawing forming a part of this specification, in which-Figure 1, represents a rocking chair showing my collapsible awningapplied thereto, the cover or canopy portion thereof being shown insection. Fig. 2, a plan view of the cover or canopy showing the tucks inwhich are inserted portions of the frame, the side flanges beingremoved. Fig. 3, a side elevation of the foraminous canopy, the skirtbeing shown in section and a portion thereof being broken away. F 4, aperspective view of the frame, showing the relation of one part to theother. Fig. 5, a side elevation of my improvement as applied to anotherform of chair, a portion of the foraminous skirt being broken away; andFig. 6, a face view of a portion of the Specification of Letters Patent.

frame illustrating the construction used when applied to certain stylesof chairs. Fig. 7 is a side elevation of a chair showing my collapsibleawning folded back to the position it assumes when not in use. Fig. 8,an edge view of a slightly modified form of frame and means to attach itto the chair. Fig. 9, a face view thereof. Fig. 10, an edge view of astill further modified form of my invention.

In carrying out my invention shown in Figs. 1 to 4 inclusive, 2represents a chair having a relatively high back, and to the side postsof the back are secured the upright frame 3 and extension frame 4:. Theupright frame is preferably formed from a single piece of metal bent toproduce a top rail 5 and arms 6, each of which is provided with a hole 7near its end and also having a notch 8 produced intermediate its length.The extension frame lis also preferably formed of a single piece ofmetal bent to form a front rail 9 and the parallel arms 10, each ofwhich is provided with a perforation 11 near its end. The perforations 7and 11 in the arms (3 andlO are brought into alinement and through thesepass an attaching screw or its equivalent 12 which is threaded into theside posts of the chair back some distance from their upper ends andwhen the awning is open and in use, the notches 8 will engage the shankof the stop screws 13 knotted in the side posts of the chair back andlimiting the forward movement of the frame. The frame members arecovered by a canopy 14: which consists of a top 15, side walls 16 andfront and back llaps l7 and 18 respectively. From the canopy are formedthe tucks 19 into which are inserted the frame members before they arefastened to the chair. When the awning is in place upon the chair, theextension member l. of the frame will be held at the desired distancefrom the upright member of the frame by the canopy, the upright memberof the frame will be held in its proper position by its contact with thestop screws 13. Since the parts of the frame are within the canopy, asthe extension mcn'iber is moved rearwardly it will cause the canopy tofollow with it and at a certain point will disengage the upright memberfrom the stop screws 13 and will cause said upright member to movebackward until the whole of the awning hangsdown from the attachingscrews 12 at the back of the chair.

If at any time while the awning is in use, the wind is blowing at asuflicient velocity to raise the awning or cause it to shake, it may betied down by suitable attaching cords 20, one end of which passesthrough the perforation in each of the arms of the extension member andthe opposite end'tied to the chair, preferably the arm thereof. As heredescribed, I have produced an awning to shade the suns rays from theperson using the chair and to overcome any possibility of being troubledwith any insects flying about, a foraminous canopy 25 may be placed inthe position which comprises the top or cover 22 of foraminous materialof the same size as the top of the'canopy 14L, and this cover isprovided with a set of hooks 23 which fasten into the eyes 24: sewn tothe outside of the top of the canopy 14. The skirt of this foraminouscanopy 25 is of foraminous material such as mosquito netting and each ofthe sections is a cord, so that no material will be gathered where it issewn to the cover 22, although the bottom thereof will be suiiicientlywide to permit uninterrupted movement of the person using the chair.

In Figs. 5 and 6 I have shown a slightly modified form of my inventionso produced as to be applicable to chairs with leaning backs and whenused with such chairs it is necessary to drop the front end of theawning in accordance with the backward movement of the chair to keep theawning on a horizontal line. In accomplishing this I form a slot 26 inthe end of each of the arms of the extension member of the frame so asto permit thebackward movement of the extension member which will lowerthe front end of the awning the desired distance. In other respects thisform of my device is the same as that shown in Fig. 1.

In Figs. 8 and 9, I have shown a further modified form of my inventionwhich will permit the awning frame to be readily and quickly adjusted tochange the position of the front edge of the awning in accordance withthe position of the chair back, so that the awning will rest in agenerally horizontal line. 27 denotes a plate of any desiredconfiguration having screw receiving holes 28 countersunk, to receivethe heads of the screws 29, whereby the plates are attached to the siderails of the chair back. In this form of my invention, I utilize theupright frame 3 and the extension frame 4 these being pivoted to theplate 27 in any desired manner here shown as being a butterfly bolt 30.Said bolt passing through the end of the extension l to the uprightframe 3 some distance from the end of the latter. The ends of the arms..6 .of the upright frame are each provided with a perforation 31 whichaline with the perforations 32, produced in the plate 27. Nhen thedesired adjustment of the awning has been obtained, a pin 33, is passedthrough the perforation 31 and into one of the perforations 32 whichwill hold the frame in the determined position. I In Fig. 10, I haveshown a plate 27 simi lar to the one illustrated in Figs. 8 and 9 whichis provided with a central projection 34: having radial serrations whichregister with the radial serrations 36 formed upon the face of theprojection 37 produced with the plate 38. Said plate being attached tothe upright frame 3 by rivets or other suitable members 39. A bolt 40having its'head countersunk in the plate 27 passes through said plate.The plate 38 and the arms of both frames and said bolt as a butterflynut 41 threaded thereon to draw the parts securely together and holdthem in the different adjusted positions. To change the adjustment,theend 41 is backed OK the bolt a short distance to permit thedisengagement of the serrations upon the projections which permits theframe to be moved about. Of course I do not wish to be limited to theexact details of construction as here shown, as these may be variedwithin the limits of the appended claims without departing from thespirit of my invention.

Having thus fully described my invention, what I claim as new anduseful, is-

1. In combination with a chair, a frame comprising an upright member andan extension member, each ofsaid members being bent from a single pieceof metal to produce a rail and parallel side arms, means for securingthe ends of said arms to a chair, a canopy covering the frame, and stopscarried by the side posts of the chair back with which the uprightmember of the frame will contact to limit the forward movement of theawning.
